Congrats Ted!
You are in for quite an adventure. Boys are easy, we don't evolve much, boys are basically just little men. Girls are a whole different story. They go from being a girl, to a lady then to a woman, they are very different at every stage.
FYI, newborns change appearance almost daily till they are a few months old, so take lots and lots of pictures for the first year.
Also, do your child a favor and do what ever it takes for her to avoid the life long agony of being a Utah Jazz fan.
